Calculate the average rate of change of function on the interval (a, a+h). simplify your expression. Show all steps. f(x)=3x+2/2x-1

Please check the explanation.

Step-by-step explanation:

Given the function

at x₁ = a,

at x₂ = a+h,

Using the formula to determine the average rate of change

Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]

as a+h-a = h, so    

Thus, the everarge rate of chnage:  

We can further simplify such as:

Cancel the common factor h

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6

care to share were the trapezoid shown is ?
